Tip for scalping in an uptrend:
If you are holding a long position on quarterlies per say, and you are scalping on perpetuals or bitfinex, it is a good idea to keep your leverage while shorting less than your leverage while longing. If you go underwater on a long position in an uptrend your risk is less than being underwater on a short. For some, this may be obvious, but it is often overlooked. Two very major supports are 15500 and 14300-14400 which is a major fib level.
